Every few years, Edgar's entire family gets together for a family reunion. This year, Edgar's parents are hosting, and they have to cook a lot of food to feed the crowd. Edgar has volunteered to do the most tedious job: shelling peas. There is a proportional relationship between the amount of time (in minutes) Edgar spends shelling peas, x, and the weight (in pounds) of the peas he has shelled, y.
The equation that models this relationship is y=0.5x.
How many pounds of peas does Edgar shell in 16 minutes? Write your answer as a whole number or decimal.

What is the image of ( 3 , − 2 ) after a reflection over the line y = x?
Answer:
(2,-3)
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and the signs are changed.
(-2, 3)
Solution:Remember, when you reflect a point over the line y=x, the x- and y-coordinates switch places.So if we had a point with the following coordinates: (4, 5) and we reflected it over the line y=x, then the coordinates of the point are (5, 4)Therefore, if we take a point (3,-2) and reflect it over the line y=x, then the coordinates of the point are now (-2, 3)Hope it helps.

Lindsay is very exited to be getting a great deal on an iPad. It was originally $500, but she will only be paying $325. What percent did she save?
heeeeeeeeeelp I'm dying.
well, the original price was 500 bucks, but went down to 325, namely 500 - 325 = 175, so she'll be saving 175 bucks.
if we take 500 to be the 100%, what is 175 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 500 & 100\\ 175& x \end{array} \implies \cfrac{500}{175}=\cfrac{100}{x}\implies \cfrac{20}{7}=\cfrac{100}{x} \\\\\\ 20x=700\implies x=\cfrac{700}{20}\implies x=35[/tex]

What do you know about a quadratic equation that has the following points (2, 0) and (10, 0)?
A. The parabola must open up.
B. The parabola will have a negative y-intercept.
C. The x-coordinate of the vertex must be 6.
D. The graph must be wider than the parent function.
Answer:
C. The x-coordinate of the vertex must be 6
Step-by-step explanation:
The parabola intercepts the x-axis when y = 0.
Therefore, if the quadratic equation has the points (2, 0) and (10, 0) then the x-intercepts or "zeros" are x = 2 and x = 10.
The x-coordinate of the vertex is the midpoint of the zeros.
[tex]\sf \implies midpoint=\dfrac{2+10}{2}=6[/tex]
Therefore, the solution is option C.
Additional Information
The leading coefficient of a quadratic tells us if the parabola opens upwards or downwards:
Positive leading coefficient = parabola opens upwardsNegative leading coefficient = parabola opens downwardsWe have not been given this information and so therefore cannot determine the way in which it opens.
As we do not know the way in which way the parabola opens, we cannot determine if the parabola will have a negative or positive y-intercept.
We have not been given the full quadratic equation, and so we cannot determine if the parabola is wider (or narrower) than the parent function.

A cone has a height of 10 yards and a radius of 9 yards. What is its volume?
Use 3.14 and round your answer to the nearest hundredth.
cubic yards
Part I: Recalling the "Volume of cone" formula
Given:
Height of cone = 10 yardsRadius of cone = 9 yardsFormula (Volume of cone):
[tex]\text{Volume of cone:} \ \dfrac{1}{3} \times \pi \times r^{2} \times h[/tex]
[Where r and h are the radius and the height respectively.]
Part II: Determining the volume of the cone
Substitute their values into the formula to determine the volume of the cone.
[tex]\implies \text{Volume of cone:} \ \dfrac{1}{3} \times \pi \times (9)^{2} \times (10)[/tex]
∴ Let π be 3.14 ∴
[tex]\implies\text{Volume of cone:} \ \dfrac{1}{3} \times 3.14 \times (9)^{2} \times (10)[/tex]
Simplify the expression to determine the volume.
[tex]\implies\text{Volume of cone:} \ \dfrac{1}{3} \times 3.14 \times 81 \times 10[/tex]
[tex]\implies\text{Volume of cone:} \ 3.14 \times 27 \times 10[/tex]
[tex]\implies\text{Volume of cone:} \ 31.4 \times 27[/tex]

Write an equation for the line in point-slope and slope-intercept forms.
Passes through (1, 2) and has a slope of 7.
point-slope form: y-y₁=m(x-x₁)
==========
y - 2 = 7(x-1)slope-intercept form: y = mx + b
==========
y - 2 = 7(x-1)y - 2 = 7x-7y = 7x - 7 + 2y = 7x -5Point slope is written as y - y1 = m(x -x1)
Where x1 and y1 are the given point and m is the slope:
point slope :
Y-2 = 7(x-1)
slope intercept is written as y = Mx + b where m is the slope and b is the y intercept:
musing the slope you have y = 7x + b
Now replace y and x with the given point to solve for b:
2 = 7(1) = b
2 = 7 + b
Subtract 7 from both sides to get b = -5
now replace b in the equation to get:
Y = 7x-5

You can prove triangles’ congruence with things called axioms (or postulates). For triangles, there are four:
(S means Side, A means Angle)
SAS
SSS
ASA
AAS
If you go round a triangle, in order (so aside, then the next angle, next side, etc.), and find that everything from one of these postulates is equal, you have two congruent triangles.
(These triangles’ sides and angles, which are marked on the image, are equal to the other’s)
This diagram shows the SAS axiom, as the equal parts of the triangle go in order of a side (Y to Z), an angle (Y to Z to X), and another side (Z to X).

Answer:
e
Step-by-step explanation:
the coordinates of the midpoint are the average of the coordinates of the endpoints.
let coordinates of C = (x, y ) , then with A = (- 1, 2 ) calculate the average and equate to the coordinates of B (3, 2 )
[tex]\frac{x-1}{2}[/tex] = 3 ( multiply both sides by 2 to clear the fraction )
x - 1 = 6 ( add 1 to both sides )
x = 7
and
[tex]\frac{y+2}{2}[/tex] = 2 ( multiply both sides by 2 )
y + 2 = 4 ( subtract 2 from both sides )
y = 2
coordinates of C = (7, 2 )
